2018 Yamaha F300 V6 4.2L Digital 30 F300UCA Outboard Motor

Need the extra reach of a longer shaft on Yamaha's top-output V6? The F300UCA carries the same digitally controlled 4.2-liter block onto a 30-inch leg, landing at 575 lbs dry, with Yamaha citing as much as a 19 percent faster cruise-rpm speed than other 300-hp four-strokes. Shaft and fitment Measure your transom against this longer shaft before anything else, since the wrong length here means re-rigging a heavy V6 rather than a quick fix. A digital-ready helm is still part of the deal on this trim, and tilt reaches 67 degrees. Power and feed Onboard sensors continually report atmospheric and running conditions back to the engine control module, which Yamaha ties to stronger fuel economy at cruising speed against other four-stroke V6s. A composite lower engine pan cuts weight while resisting corrosion, and the console display offers a touchscreen option alongside digital controls. Trim moves between -3 and +16 degrees on this build, and tilt reaches 67 degrees as well. Pair this with a stainless prop if your boat tends to run heavy with passengers and gear aboard, since the extra blade strength handles higher loads better than aluminum. Three years covers both pleasure and government use on this engine, with commercial use covered for one year. Confirm rigging compatibility with us before ordering, and ask us which shaft length your current bracket needs.
